问题描述

在某些情况下、在执行asfd设置的克隆操作期间、renamedg会失败、并显示Linux unsupported错误：

为此、Oracle支持人员建议 /dev/mapper/.. AFD:* 、在处理AFD受管磁盘时、应使用、而不是使用作为ASM_diskstring。
But将ASM_diskstring更改为only afd:*后，如下图所示，renamedg仍将dev/maper作为ASM_diskstring。

[grid@nctest ~]$ asmcmd dsget
 parameter:AFD:*
 profile:AFD:*

 NAME                                 TYPE                              VALUE
 ------------------------------------ --------------------------------- ------------------------------
 asm_diskstring                       string                            AFD:*

尽管 /dev/mapper asm_diskstring 已修改源数据库并为克隆创建了新备份、SCO仍会将其作为进行接管。
